Field evidence of seed coating with the degrading bacterium mitigating atrazine risks to soybeans in black soils

-
  Field evidence demonstrates that seed coating with atrazine-degrading bacteria is an effective, eco-friendly strategy to mitigate herbicide risks to soybeans grown in black soils . Atrazine residues in black soils often persist due to high organic matter and limited microbial degradation, leading to phytotoxic effects on sensitive crops such as soybean. Field trials show that coating soybean seeds with specialized atrazine-degrading bacterial strains enhances rhizosphere microbial activity, accelerates atrazine breakdown, and significantly lowers residual toxicity during early crop establishment. This biological seed treatment improves seedling emergence, root development, nodulation, and overall plant vigor while maintaining weed control efficiency. Moreover, the approach reduces atrazine leaching and accumulation in soil–plant systems, supporting soil health and microbial diversity. The results highlight seed coating with degrading bacteria as a sustainable agronomic practice ...

  Recent advances in the understanding of silicon in the soil–plant system highlight its emerging role as a beneficial element for sustainable agriculture and environmental resilience. Although not classified as an essential nutrient for most crops, silicon significantly enhances plant growth, productivity, and stress tolerance. Modern research reveals that silicon improves soil physical properties by promoting aggregation, enhancing water retention, and reducing nutrient leaching, thereby creating a more favorable root environment. In plants, silicon uptake and transport mechanisms have been clarified at the molecular level, with the identification of specific silicon transporter genes that regulate its accumulation in roots and shoots. Silicon deposition in plant tissues strengthens cell walls, improves mechanical stability, and enhances resistance against pests, diseases, drought, salinity, heavy metal toxicity, and temperature extremes. Advances in nano-silicon fertilizers and ...

Soil Bioresource Applications and Environmental Sustainability

-
Image
  Agriculture is the backbone of global food security and rural livelihoods, playing a vital role in economic development, environmental stewardship, and social well-being. Modern agriculture integrates traditional knowledge with scientific innovations to enhance crop productivity, soil fertility, and water-use efficiency while minimizing environmental impacts. Sustainable agricultural practices such as conservation tillage, crop diversification, integrated nutrient management, and precision farming help maintain soil health, conserve biodiversity, and improve resilience to climate change. Advances in biotechnology, digital agriculture, and climate-smart farming enable farmers to optimize inputs, reduce losses, and adapt to changing agro-climatic conditions. Agriculture also contributes to ecosystem services by supporting carbon sequestration, nutrient cycling, and landscape sustainability. By promoting resource-efficient and environmentally responsible farming systems, agriculture...

Belowground Interactions and Implications for Nutrient Use Eco-Efficiency in Cropping Systems

-
Image
  Belowground interactions play a critical role in determining nutrient use eco-efficiency in cropping systems by regulating how plants access, transform, and retain essential nutrients in the soil environment. These interactions involve complex networks among plant roots, soil microorganisms, and soil physical and chemical properties. Root architecture and exudation patterns influence microbial activity by supplying carbon substrates that stimulate beneficial microbes such as mycorrhizal fungi and plant growth–promoting rhizobacteria, which enhance nutrient mobilization, particularly of nitrogen and phosphorus. At the same time, microbial processes such as mineralization, immobilization, and nitrification govern nutrient availability and losses. In diversified cropping systems, including intercropping and crop rotations, complementary root traits and temporal niche differentiation reduce competition and improve overall nutrient capture. Improved belowground biodiversity also enhan...
